Braking Efficiency May Be Affected - Unimog (2015)

Fault: It has been established that Oil Carbon and Granulated Dust contamination could cause the ventilation function of the Shutoff and Safety Valve to be impaired. The internal air pressure of the Safety Valve can therefore increase from 18.5bar to over 40bar. This can result in the failure/rupture of the top section of the housing of the air drier cartridge. The brake system will remain operation to enable the driver to bring the vehicle to a control stop after they hear the rupture.

Seat Base May Crack - Actros Antos & Arocs (2015)

Fault: The Front radius angles in the driver?s and passenger metal seat base may not have been formed correctly and as a result the seat base may suffer from stress cracks which could compromise the strength of the seat base in the unlikely event of a rear end collision. The seat belt system is an integrated part of the seat.

Repair: Recall the vehicles that are likely to be affected to replace the driver and passenger seat bases.
